This scoping review will evaluate and synthesise what is known about the impact of structural and social determinants of health on neurodegeneration among adults of African American or Black (AAB) racial identity with a history of traumatic brain injury (TBI). The primary objective is to examine how structural factors, such as healthcare access, influence disparities in neurodegeneration following TBI. Given higher rates of TBI and worse outcomes among Black individuals compared with White individuals, this review seeks to fill the gap in research concerning underrepresentation of AAB populations.

Guided by the Joanna Briggs Institute Evidence framework, this review will systematically search PubMed (MEDLINE), Embase and Cochrane CENTRAL Library (Wiley) for relevant studies. Eligible studies will involve adult human participants diagnosed with neurodegenerative conditions, including dementia and cognitive impairment, and with a history of TBI. Studies must include participants of AAB and non-Hispanic White (NHW) racial identity to facilitate comparisons. The review will focus on identifying potential factors contributing to disparities in neurodegeneration. Data synthesis will include narrative summaries, comparative tables and visualisations to highlight racial disparities in neurodegeneration risk and AAB representation in TBI research. This approach is its structured framework will evaluate the depth of racial inclusion across studies, allowing for a more nuanced understanding of how structural and social determinants shape outcomes.

As this review involves only previously published literature, institutional review board approval will not be required. The findings will be disseminated through peer-reviewed publications, conference presentations and lay summaries.

The National Health Service Cervical Screening Programme (NHSCSP) currently involves a healthcare professional collecting a cervical sample in a healthcare setting. This method of screening has barriers associated with access to screening appointments and the poor acceptability of the speculum examination. Primary screening through HPV testing has led to the development of self-sampling screening methods including vaginal and urine self-sampling, with many UK studies comparing these screening methods with the current NHSCSP. It is not known what features of self-sampling influence individuals’ preferences and cervical screening uptake. To understand these preferences, we plan to undertake a discrete choice experiment (DCE). This protocol aims to describe the steps taken to design the DCE and the proposed approach to fielding the DCE to identify preferences for different sampling approaches in cervical screening.

An online survey comprising a DCE was designed to understand preferences of individuals for self-sampling methods within the NHSCSP. Attributes and levels for the DCE were generated through an iterative process including a literature review of qualitative studies about self-sampling cervical screening methods, input from cervical screening clinical experts and a patient and public involvement group (n=6). A D-efficient design was used to create choice sets for the DCE survey. Regression-based analysis will be used to estimate the impact of each attribute and level on individual choices.

This study has been approved by The University of Manchester Proportionate Research Ethics Committee (2024-20767-37669). The results of the DCE will be submitted for publication in a relevant peer review journal and the results will be presented at national and international conferences.

There are no data associated with this protocol. The data produced by this study and analysis scripts will be made available in a public repository following publication of the study.

Stroke is a leading cause of death and disability in the Caribbean, yet there is limited published information on the availability and utilisation of diagnostic imaging and treatment methods. Inequities in healthcare infrastructure, access to neuroimaging and acute treatment options may contribute to poorer outcomes following stroke, particularly in the low-resource settings that characterise most of the Caribbean region. The objective of this review is to map the literature on access to diagnostic and therapeutic modalities for adult stroke care in the Caribbean to identify potential limitations in acute treatment and examine how restricted access may impact outcomes. The resulting data can help inform strategies for improving access to stroke care in resource-limited communities.

We will apply a three-step strategy based on the Joanna Briggs Institute methodological framework: first, a limited search to identify relevant articles; second, selection of key search terms; third, implementation into a comprehensive search strategy. The query will range from 1 January 1995 to 1 June 2025 (date of final search). Search results will be extracted and screened by two independent reviewers, and findings will be presented in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. We will consider studies focusing on ischaemic and haemorrhagic stroke in the Caribbean, emphasising access to diagnostic imaging, stroke centres, prehospital management and emergent treatment. Studies examining acute stroke management capacity within the region will be considered. Studies will be excluded if they: focus exclusively on primary stroke prevention, postacute care, longitudinal care pathways for stroke victims or paediatric populations; are unrelated to stroke diagnosis or treatment or are conducted outside the Caribbean.

This protocol aims to perform secondary analysis of previously published literature; therefore, ethical approval is not required. The results of this review will be disseminated through academic conferences and peer-reviewed publication.

Several antibiotic stewardship interventions have been proven effective and safe for reducing the high number of antibiotic prescriptions in late preterm and term neonates at risk of early-onset sepsis (EOS). For successful translation of EOS interventions to clinical practice, implementation strategies should be employed targeting stakeholders. The primary aim of this study is to assess the impact of implementing an antibiotic stewardship bundle, including the EOS calculator, procalcitonin-guided therapy and intravenous-to-oral switch therapy on antibiotic exposure for EOS in Dutch secondary hospitals. Secondary aims are to examine additional clinical outcomes and implementation outcomes.

We will conduct a multicentre, prospective implementation study with interrupted time series and before-after analyses at the paediatric or specialised neonatal departments of 11 Dutch secondary hospitals and their surrounding neonatal care networks. A multimodal implementation strategy, designed using Implementation Mapping, is employed to facilitate implementation. The study population is twofold: (1) neonates born at 34 weeks of gestation or later with suspected EOS that will receive intervention-related care and (2) paediatricians, paediatric residents, neonatal nurses, maternity nurses and parents who are the focus of the implementation strategies. The primary outcome is days of antibiotic therapy per 1000 live-born neonates, which will be evaluated using interrupted time series analysis as well as before-after comparison. Secondary clinical outcomes will be assessed by comparing clinical data from the 12 months pre-implementation and post implementation. Implementation outcomes are adoption, fidelity, feasibility and acceptability of the interventions and fidelity and appropriateness of the implementation strategies. Implementation outcomes will be assessed using both qualitative and quantitative methods, including surveys, individual interviews and focus group interviews. A mixed-methods approach will be used to integrate clinical and implementation outcomes.

The Medical Ethics Committee United (MEC-U) declared (reference: W24.132) that this study does not fall under the Dutch Medical Research Involving Human Subjects Act (WMO). Subsequently, ethical approval was granted by the Scientific Committee of the Franciscus Hospital (T110). The scientific committees of all participating sites adopted this decision and granted permission for local conduct of the study. As electronic health record data are sampled retrospectively and anonymously, a waiver of consent was given to collect these data. Informed consent will be obtained from participants completing surveys or taking part in interviews and focus group discussions. The findings will be disseminated through journal publications and conference presentations. Furthermore, practice and policy recommendations will be collaboratively developed with partner organisations.

Intraoperative anaesthesia handoffs represent a risk point in the care of surgical patients. Although often necessary to prevent fatigue, improve vigilance and optimise operational efficiency, critical information can be lost, potentially leading to postoperative complications. Structured handoffs can increase the transfer of knowledge during intraoperative anaesthesia handoffs, improving their quality. We therefore propose to test the primary hypothesis that a semi-structured intraoperative anaesthesia handoff cognitive aid reduces the number of serious 30-day complications in surgical patients.

We will enrol adults having non-cardiac surgery who are scheduled to have an intraoperative anaesthesia handoff for operational reasons. We plan a cluster randomised trial (enrolling over 18 months, anticipated sample size approximately 4500 patients) that will compare the Epic Electronic Health Record intraoperative anaesthesia handoff cognitive aid to routine handoffs. Our primary outcome will be the number of serious postoperative complications within 30 days. Our secondary outcomes will be: (1) the number of minor complications; and (2) the duration of postoperative hospitalisation. Bayesian analysis with generalised linear multilevel modelling will be used to estimate the effect of structured handoffs on the primary and secondary outcomes.

This study has been approved by the local institutional review board with a waiver of informed consent. Results will be disseminated in the medical literature with de-identified data available on request.

To assess the association of normal systolic blood pressure maintenance (SBP_maintain) with coronary artery calcification (CAC) progression in non-diabetic and diabetic subjects at low to intermediate cardiovascular risk.

Retrospective cohort study with a mean follow-up of 3.3 years.

Data from the Korea Initiatives on Coronary Artery Calcification registry were analysed.

10 754 asymptomatic Korean adults (51.5±8.6 years; 84.5% male; 14.2% diabetes) were enrolled. Participants were divided into two groups: normal SBP_maintain (maintain (≥120 mmHg) at the time of follow-up CAC scan.

CAC progression was defined as a difference of ≥2.5 between the square roots () of the baseline and follow-up coronary artery calcium score (CACS) (transformed CACS). Annualised transformed CACS was defined as transformed CACS divided by the interscan period.

Compared with non-diabetics, the incidence of CAC progression was higher in diabetics (28.4% vs 47.3%, pmaintain was inversely associated with an annualised transformed CACS (β: –0.18, 95% CI: –0.25 to –0.12, pmaintain showed a lower risk of CAC progression than ≥elevated SBP_maintain in non-diabetics; however, this association was not observed in patients with diabetes.

Maintaining normal systolic blood pressure was associated with a significantly attenuated CAC progression, especially in clinical conditions without established diabetes.

Type 2 diabetes is a prevalent chronic disease, associated with health complications, premature morbidity and significant healthcare costs. Optimal lifestyle behaviour control and patient self-management are crucial for improving diabetes control; however, they are difficult to achieve in primary care. There is limited research on the use of information from wearable devices to encourage behaviour change. This study will examine the effectiveness and cost-effectiveness of a multi-component health behaviour intervention in achieving clinically significant reductions in haemoglobin A1c (HbA1c) among general practice patients with type 2 diabetes.

The study uses a cluster-randomised controlled design, with general practices randomly assigned to either the Wearables Integrated Technology (WEAR-IT) intervention (n=15) or usual care (n=15). To achieve a sample size of 375 participants, 12–13 patients per practice will be recruited. Patients diagnosed with type 2 diabetes will be eligible to participate if they are aged 18–75 years; have had poorly controlled diabetes (HbA1c≥7.5%), with the cognitive capacity and ability to access the intervention application via an iOS or Android smart device. The WEAR-IT self-management intervention combines information from wearable devices (physical activity, blood glucose and blood pressure) and the electronic medical record, with goal setting and coaching support. The intervention will be primarily delivered by the general practice nurse, with review and confirmation of goals by the general practitioner. Participants attending the usual care practices will receive standard care. Outcome measures, including HbA1c, lipids, blood pressure, quality of life, dietary and exercise behaviours and cost-effectiveness, will be collected at baseline, 6-month (primary endpoint) and 12-month post-randomisation. The primary analysis will compare the change in HbA1c between the intervention and control groups at 6-month follow-up, with long-term outcomes assessed at 12-month post-randomisation.

The study was approved by Bond University (BH00137). Results will be disseminated through peer-reviewed journal publications, conference presentations and summaries to participating sites and patients.

Inhaled anaesthetics can be used in mechanically ventilated critically ill patients to provide sedation. This approach to sedation potentially improves patient and health system outcomes, but further supportive evidence is needed. The objective of the SAVE-ICU clinical trial is to compare the effectiveness of inhaled versus intravenous sedation in ventilated adults with acute hypoxaemic respiratory failure.

SAVE-ICU is a multicentre, open-label, pragmatic, randomised controlled trial conducted in 15 intensive care units (ICUs) in Canada and the USA. Eligible patients include mechanically ventilated and sedated adults with acute hypoxemic respiratory failure from COVID-19 or non-COVID causes with PaO₂/F_IO₂ ratio 12 hour). A hierarchy of outcomes was identified at the time of trial design, as the trial was launched during the COVID-19 pandemic when study drug shortages, staffing challenges and healthcare system pressures were prevalent and there was a requirement for rapid evidence generation and implementation on this topic. The primary outcome and highest in the hierarchy is hospital mortality (requiring 758 participants). Secondary and lower hierarchical outcomes are ventilator-free days at day 30 (200 patients), quality of life at 3 months (144 participants) and ICU-free days at day 30 (128 participants). Additional secondary outcomes include median daily oxygenation at day 3 (PaO₂/F_IO₂ ratio), need for adjunctive acute respiratory distress syndrome therapies (prone positioning, inhaled nitric oxide, paralysis with a neuromuscular blocking agent and extracorporeal membrane oxygenation) during ICU stay, days alive and free from delirium and coma at day 14, hospital-free days at day 60 and disability score at 3 months and 12 months after enrolment.

The protocol was approved by all hospital ethics committees and by Health Canada. Informed consent will be obtained from substitute decision makers or deferred consent (as permitted by site ethics board). Trial findings will be shared at the end of the study using peer-review publications, conference presentations and social media as part of the trial knowledge translation plan.

NCT04415060.

Different malaria control measures are deployed simultaneously in endemic settings globally, with varying impacts on malaria burden. In sub-Saharan Africa, which bears the greatest burden of malaria, evidence on the impact of implementing various control interventions on malaria immunity remains unknown. This systematic review seeks to collate evidence on the extent of progression from uncomplicated to severe malaria among populations in sub-Saharan Africa settings receiving concurrent deployment of various malaria control measures.

The review will use a priori criteria contained in the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. An experienced librarian (AAK) will independently search for articles from the following databases: PubMed, Web of Science, Embase, Scopus and Google Scholar. Boolean operators ‘AND’ and ‘OR’ will be used in the article search. Identified articles will be managed using EndNote. Article screening for inclusion and data extraction will be done in duplicate by two reviewers (EJO, and BM). Data extraction tools will be developed and customised in Excel. Data will be analysed using both narrative and quantitative synthesis. The level of heterogeneity between study outcomes will be measured using the I² statistic. Subgroup analysis will be conducted to explore heterogeneity and establish the impact of different control interventions on progression from uncomplicated to severe malaria. A full systematic review and meta-analysis is expected to be ready for dissemination by the end of December 2025.

This study did not involve human participants and so ethical approval was not sought. A full review and a meta-analysis will be published in a peer-reviewed journal and presented at national and international conferences.

Traumatic brain injury (TBI) is a leading cause of mortality and disability worldwide. In the USA, individuals who racially identify as African American or Black experience disproportionately higher rates of TBI and sustain worse prognosis compared with White patients; however, this population continues to be under-represented in contemporary translational research agendas. This protocol aims to comprehensively evaluate and synthesise what is currently known about the molecular epidemiology of TBI outcome among individuals of Black racial identity or African ancestry.

This review will use the established scoping review framework from the Joanna Briggs Institute. The search strategy will be implemented in PubMed (MEDLINE) and expanded to Embase and Cochrane CENTRAL Library (Wiley) databases in the final review. The date range will span from database inception to 20 July 2025 (date of final search). A two-stage screening process will be performed first at the title and abstract level before full-text assessment. Screening will be performed by two independent reviewers and discrepancies will be reconciled by a third reviewer. Articles that meet the following inclusion criteria will be considered: we will include human studies that investigate molecular and biochemical markers associated with TBI outcome. Studies must include individuals who are (A) of Black or African American racial identity, (B) of African ancestry and/or (C) performed in Sub-Saharan African countries. There is no eligibility criteria related to participant age, sex or gender. Eligible studies will be limited to English, Spanish or French. Data extracted from will be analysed and presented as written narrative, summary statistics of study characteristics and graphical or tabular displays.

Ethical approval is not required for this scoping review. The results of this review will be disseminated through peer-reviewed publications and academic conferences.

Ages of attainment for early gross motor milestones have been widely studied, but definitions and measurement methods have varied greatly. Since delays in motor milestones have been used extensively as one of the earliest indicators of atypical development, it is imperative to establish a universal understanding of the methods and results reported on motor milestones in typically developing children. Therefore, the primary aim of this scoping review is to provide an overview of recent studies reporting ages of onset for independent sitting and walking in typically developing children worldwide; this will be achieved by summarising how these milestones have been operationalised and evaluated, the samples from whom these data have been drawn, and the reported ages of acquisition.

To meet inclusion criteria, articles must: be original research papers published in any language since 2003, contain a sample of typically developing children and report actual ages of onset for independent sitting and/or walking. To conduct this scoping review, the Joanna Briggs Institute methodological framework will be used. Search terms will include variations of the following concepts: acquisition of motor milestone (independent sitting and/or walking), age of onset, infancy. Six databases (CINAHL Plus, Embase, PsycNet: PsycINFO & PsycArticles, PubMed, Scopus, Web of Science: Core Collection) will be searched. Records from these databases will be screened for eligibility. Two people will independently review each record during title and abstract screening, and three people will independently screen full texts and extract data. Results will be displayed in tables, graphs and narrative summaries in the scoping review.

As the review will only include previously published data, ethics approval is not required. Findings will be shared at scientific conferences and in a peer-reviewed journal.

Aboriginal and Torres Strait Islander people living with disability have unequal access to health and disability support services. The impacts of colonialism and the deficit-based, Western medical model of disability have been identified as barriers to services in remote Aboriginal communities. This study explored different perceptions of disability and identified strategies to help bridge the gap between Aboriginal community members in the Fitzroy Valley and Western health and disability support services.

Aboriginal Participatory Action Research approach with in-depth interviews. Transcripts were analysed using reflexive thematic analysis. Preliminary results were presented to community representatives for contextualisation, validation and to co-design recommendations.

Fitzroy Valley in the Kimberley region, Western Australia.

Aboriginal community members with lived experience of disability (n=7) and health and disability support service providers (n=12).

Eight themes were identified: (1) Aboriginal kinship systems are a community strength and support for people living with disability; (2) Aboriginal people from the Fitzroy Valley perceive disability as a social construct; (3) Western medical model of disability differs from Aboriginal perceptions of disability; (4) Aboriginal people from the Fitzroy Valley perceive different types of disabilities in various ways; (5) good awareness of fetal alcohol spectrum disorder in the Fitzroy Valley, but more education is wanted; (6) focus on functional needs and supports for disability; (7) barriers to disability services and (8) decolonise disability services. Community co-designed recommendations focus on centring the Aboriginal worldviews of disability in the Fitzroy Valley.

Decolonising disability services is needed to improve access for Aboriginal and Torres Strait Islander communities. This should involve adapting the current Western medical model of services to enable strengths-based diagnostic and support services that align with Aboriginal and Torres Strait Islander kinship systems, cultures and ways of being. Community leadership must play a central role in this shift.

Ventilation tube insertion for paediatric otitis media (POM), including acute otitis media (AOM) and otitis media with effusion (OME), has been signalled in the past for potential unwarranted treatment variation. Quality improvement initiatives, like Audit & Feedback (A&F), often ignore the care pathway when identifying such variation, possibly overestimating variation at a specific care step. To gain more insight into the effect of prior care steps, this study examined (1) the degree of regional variation in each step of the care pathway (general practitioner (GP) contacts, referrals and surgeries) and (2) investigated the effect of adjusting for prior care steps.

Observational study using general practice electronic health record data linked to specialist claims data.

272 790 children ≤12 years with and without POM registered in 320 GP practices between 2017 and 2018.

Using multilevel logistic regression, the degree of regional variation in each step of the POM care pathway was assessed by calculating the coefficient of variation (CV).

The effect of adjusting for prior care steps was determined by estimating correlations between subsequent care steps and analysing the impact on the CV.

Regional variation in POM treatment was larger in each subsequent step in the care pathway (CV POM GP contacts 0.110; referral 0.179; surgery 0.239). In regions with a higher proportion of children with frequent AOM/persistent OME, referral rates were higher (POM: OR: 1.06; 95% CI: 1.02 to 1.11) and surgical rates were higher (for OME only: OR: 1.08; 95% CI: 1.02 to 1.15). Regional variation in referrals and surgery decreased after adjusting for the regional frequent AOM/persistent OME rate (CV referrals POM 0.103 vs 0.128; CV surgery OME 0.047 vs 0.059).

Regional variation is observed in GP contact rates for POM and is larger in referrals and surgeries. Adjusting for the proportion of frequent AOM/persistent OME significantly reduces regional variation in POM treatment. Future A&F should adjust for prior care processes and develop tailored interventions for quality improvement.

Sepsis is a major cause of death both globally and in the United States. Early identification and treatment of sepsis are crucial for improving patient outcomes. International guidelines recommend hospital sepsis screening programmes, which are commonly implemented in the electronic health record (EHR) as an interruptive sepsis screening alert based on systemic inflammatory response syndrome (SIRS) criteria. Despite widespread use, it is unknown whether these sepsis screening and alert tools improve the delivery of high-quality sepsis care.

The Sepsis Electronic Prompting for Timely Intervention and Care (SEPTIC) master protocol will study two distinct populations in separate trials: emergency department (ED) patients (SEPTIC-ED) and inpatients (SEPTIC-IP). The SEPTIC trials are pragmatic, multicentre, blinded, randomised controlled trials, with equal allocation to compare four SIRS-based sepsis screening alert groups: no alerts (control), nurse alerts only, prescribing clinician alerts only, or nurse and prescribing clinician alerts. Randomisation will be at the patient level. SEPTIC will be performed at eight acute-care hospitals in the greater New York City area and enrol patients at least 18 years old. The primary outcome is the percentage of patients with completion of a modified Surviving Sepsis Campaign (SSC) hour-1 bundle within 3 hours of the first SIRS alert. Secondary outcomes include time from first alert to completion of a modified SSC hour-1 bundle, time from first alert to individual bundle component order and completion, intensive care unit (ICU) transfer, hospital discharge disposition, inpatient mortality at 90 days, positive blood cultures (bacteraemia), adverse antibiotic events, sepsis diagnoses and septic shock diagnoses.

Ethics approval was obtained from the Columbia University Institutional Review Board (IRB) serving as a single IRB. Results will be disseminated in peer-reviewed journal(s), scientific meeting(s) and via social media.

Aboriginal people in the Kimberley are concerned that scientific research, government Inquiries and Royal Commissions are not adequately informing policy and service design. In this protocol paper, we outline our proposed scoping review to identify and provide a broad overview of scientific literature regarding the health, well-being, mental health, disability, education and social outcomes of children and adolescents living in the Kimberley region of Western Australia and the recommendations that came from them.

This scoping review is guided by Arksey and O’Malley’s (2005) methodological framework. We will conduct a comprehensive search across multiple databases using several search engines. Inclusion criteria were established to inform the selection of papers to be included in the review. After de-duplication, all titles and abstracts will be reviewed, followed by full-text screening. A second reviewer will independently screen 20% of the titles, abstracts and full texts. Two reviewers will discuss discrepancies, and a third reviewer will resolve any disagreements that may arise. We will use a data extraction template in Covidence to systematically extract relevant data.

This scoping review does not require ethics approval, as we are investigating the breadth of existing literature regarding the outcomes of children and adolescents in the Kimberley, Western Australia. The scoping review results will be published in peer-reviewed journal(s) and shared with relevant policymakers to help inform future policies and service improvements and designs in the region.

To assess cervical cancer screening positivity rates, follow-up rescreening uptake 1 year after treatment and persistent positivity among women with initial positive screening results in Ethiopia. The study also explored reasons for loss to follow-up and preferences for reminder strategies.

Longitudinal cross-sectional study.

10 primary healthcare facilities in Oromia and southern and central Ethiopia.

From November 2022 to April 2024, 17 586 women screened for cervical cancer. Of these 768 (4.4%) had positive screening results, and 515 women treated at the primary level were included to assess follow-up rescreening uptake. An additional 139 women who did not return for follow-up were interviewed to identify reasons for non-uptake and reminder preferences.

Of the 515 women included in the analysis, 179 (34.8%, 95% CI: 30.6% to 38.8%) returned for follow-up rescreening. Among those re-screened, the persistent visual inspection with acetic acid (VIA) positivity rate was 16.1% (95% CI: 11.0% to 21.7%). Factors significantly associated with follow-up rescreening uptake included age over 40 (adjusted OR (AOR): 2.5; 95% CI: 1.34 to 5.00), urban residence (AOR: 1.7; 95% CI: 1.15 to 2.58), secondary or higher education (AOR: 2.0; 95% CI: 1.06 to 4.12) and HIV-positive status (AOR: 2.4; 95% CI: 1.27 to 4.87). Among the 139 women contacted, the main reasons for non-uptake were lack of time, forgetting appointments, visiting another facility and pregnancy. Regarding preferred reminders, 93% favoured text messages and all agreed to phone calls or home visits.

One-third of women adhered to follow-up rescreening after a positive cervical cancer screening in Ethiopia, revealing a considerable gap since those women had a three times higher chance of being VIA positive compared with the first screening. Older age, urban residence, higher education and HIV-positive status were significantly linked to follow-up rescreening uptake. Addressing barriers such as time constraints and forgotten appointments through tailored reminder strategies is essential for improving the follow-up rescreening uptake. Contextualised interventions can strengthen rescreening for finding those women at very high risk for cervical lesions and strengthen cervical cancer prevention in Ethiopia.

Primary care nurses (PCNs) are the second largest workforce in primary care and play a critical role in facilitating access to coordinated care and reducing health disparities. There is renewed interest in team-based primary care as a solution for health workforce challenges. Some team models enable PCNs (ie, nurse practitioners, registered nurses, licensed/registered practical nurses) to leverage one another’s expertise to work to optimal scope; the extent to which this happens depends on multiple context-dependent factors. We will conduct an umbrella review to synthesise and compare international knowledge syntheses focused on scope of practice enactment (ie., roles and activities) of PCNs in primary care.

We will conduct the umbrella review according to the Joanna Briggs Institute methodology, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P) guidelines, and using the Nursing Care Organization Framework as guidance. We will search a wide range of scientific electronic databases and grey literature sources, and consider articles published in English and French by the Organization for Economic Cooperation and Development and designated key partner countries for inclusion, with no publication date limits. Two independent reviewers will screen titles, abstracts and full-text articles, and any disagreements will be resolved through discussion or by a third reviewer. We will use the Risk of Bias Assessment Tool for Systematic Reviews to assess the quality and risk of bias in the included systematic and scoping reviews.

Results will be presented in a PRISMA Scoping Review flow diagram. We will synthesise data from included studies in a detailed literature review table and develop visual aids to communicate the shared and unique roles and activities of PCN scope of practice. We will disseminate the results of the review through peer-reviewed publications and conferences related to this field. Ethics approval is not required.
